Abstract

The method for investigating the viscoelastic behaviour of a material, especially of the elastomer or elastomeric mixture type, in which: - a specimen of the said material is subjected to at least one compression or compression-maintaining phase (D, M); - data is recorded relating to the stresses to which the said specimen (E) is subjected and/or to the deformations of the said specimen during and/or after the said compression phase; - characteristic parameters of the said viscoelastic behaviour are calculated from these data; is characterised in that, during the said compression phase, the said specimen (E) is subjected to at least one constant-rate deformation (D, D1, D2). The apparatus especially enables this method to be implemented.
